PARKER DEXTER, OF CLINTON, IOWA.

Specification forming part of Letters Patent No. 38,036, dated March 31, 1863.

To @ZZ whom it may concern.-

Be it known that I, PARKER. DEXTER, of Clinton, in the county of Clinton and State of Iowa, have invented a new and Improved Machine for Bunching and Pressing Shingles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference bein g had to the accompanying drawings, making a part of this specification, in which- Figure l is a side view of my invention; Fig. 2, a plan or top view of the same 3 Fig. 3, atransverse vertical section of the same, taken in the line .fr Fig. l. Fig. 4 is a perspective view of a bunch of shingles.

Similar letters of reference indicate corresponding parts in the several figures.

rIhe object of this invention is to obtain a machine of simple and economical construction by which a suitable number of shingles maybeadjustedcompactly togetherand bunched or bound together so as to form a bundle.

The invention consists in the employment or use of two folding end boards or plates attached to a suitable frame and used in connection with eccentrics placed on a suitable shaft in the frame and arranged with clamps, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a horizontal frame, which is constructed of two parallel bars, a a, connected by cross-ties b b. On one end of this frame there is secured a board, c, which is designed to serve as a seat for the operator.

B is a shaft which is tted transversely in the frame A, and has four eccentrics, C C D D, upon it. The eccentrics C C are at the outer sides of the bars a a of the frame A, and the eccentrics D D at the inner sides of the same, the eccentrics C being in a reverse position on the shaft B, to the eccentrics D, as shown in Fig. 3. On one end of this shaft B there is placed a lever, E. In each bar a, directly over the shaft B there is made a vertical slot or opening, b', in which loose or sliding plates F are fitted, said plates projecting over the eccentrics D D, as shown clearly in Fig. 3.

G G are vertical bars or yokes, the lower parts of which are fitted on vertical guides c o at the outer sides of the bars c a, and are allowed to slide freely up and down on them.

The lower parts of these bars or yokes are each provided with a recess, d, at their outer sides, said recesses having their upper and lower edges parallel with each other. The eccentrics C G work within the recesses d d of the bars or yokes G G, as shown clearly in Fig. 3. In the upper parts of the bars or yokes G G there are tted screws H H-one in each-and on the upper ends of said screws there are horizontal, bent, or right-angular bars l I, one on each. The bars I I, it will be seen, may be raised or lowered by turning the screws H H.

J J represent two end boards or plates which extend the whole width of the frame A. These end boards have vertical metal angleplates e attached to their ends, and the lower ends of said plates c are attached by joints or hinges f to upright plates g, which are secured to the sides of the frame A. The lower ends of the plates e, at one side of the end boards and below the joints or hin ges f, are connected by joints or pivots li to arms it', the inner ends of which are connected by pivots j j to leve s 7c k, which are secured by fulcrum-pins Z l to the side of the frame A, and have toothed segments m m at their inner ends, said segments gearing into vertical racks n at the sides of the lower parts of the vertical bars and yokes G. G. (See more particularly Fig. l.)

The operation is as follows: The lever E is in the first place so turned or adjusted as to bring the end boards J J in a vertical position, as shown in blue tint in Fig. 1, and the lower cross-bar, o, of the band (see Fig. et) is placed on the plates F in the slots or openings b. The shingles are then laid on the frame A, between the end boards, J J, the buts being outward and resting on the cross-ties b b and the points or inner ends overlapping each other and supported by the cross-bar o. The end boards,J J ,form guides to admit ofthe shingles being laid in proper position, and when a sufcient number of shingles have been laid on the frame A to form a bundle, the operator raises the lever E and thereby turns outward the end boards, J J, to a horizontal position, as indicated by the red outline in Fig. 1. Simultaneously with this outward movement of the end boards, J J, which is produced by the racks n of the yokes G, the segment-levers k, and arms z', the eccentrics C C D D respectively draw down the yokes G and bars I and elevate the plates F, the latter pressing upward the lower cross-bar, o, of the band, and the bars I pressing down upon the upper bar, p, of the same. By this means the shingles are compressed and compacted snugly together, and When this is accomplished the operator nails the upper ends of the sides q of the band to the ends ofthe upper band, o, the lower ends to the sides q having been previously nailed to the ends of the lower bar, o. The sides g may be of hoopiron.

I would remark that at the commencement of the operation the bars I are turned outward, so that they Will not interfere with the placing of the shingles onthe frame. 'Y

PARKER DEXTER.
